Math Problem Statement
describe the graph of g(x)=(x-3)^3 as a transformation of f(x)=x^4
Solution
The function can be described as a transformation of the function , though the two are different types of polynomial functions: one is cubic, the other quartic. Let's break down the transformation conceptually.
General Comparison:
-
Base Function Types:
- is a quartic function (degree 4), which has a different shape compared to , a cubic function (degree 3).
- Quartic functions typically have a "wider" parabolic-like shape, while cubic functions have an "S" shape with inflection points.
-
Transformation of Function:
- While and are different types of functions, one transformation concept can still apply: horizontal translation.
-
Horizontal Shift:
- The graph of is a shift of the standard cubic function , not .
- Specifically, the transformation is a shift 3 units to the right. This comes from the inside the parentheses. The graph of is moved so that the inflection point at is now at .
Conclusion:
The graph of is best described as a rightward horizontal shift of the cubic function , by 3 units. It doesn't relate directly to the quartic function , since their shapes and degrees are different.

Here are 5 related questions to consider:
- How do horizontal and vertical transformations differ for polynomial functions?
- What is the shape of the graph of and how do its key features change when transformed?
- What does the degree of a polynomial function say about its general shape and behavior?
- How does a horizontal shift affect the inflection point of a cubic function?
- How would additional transformations, like vertical stretching or reflection, affect the graph of a cubic function?
Tip: When transforming functions, always focus on how changes to the equation affect the shape, position, and orientation of the graph.
